Specification of Letters Patent.

Patented Feb. 8, 1910.

Application filed December 19, 1906. Serial No. 348,509.

To all whom it may concern:

Be it known that I, EDWIN V. SWAN- onnx, a citizen of the United States,residing in Maywood, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Can-Body-Flanging Machines, ofwhich the following is a specification.

My invention relates to improvements in machines for Hanging bodies ofsheet metal cans or other vessels preparatory to seaming the heads orcovers thereon.

The object of my invention is to provide a can body Hanging machine of asimple, strong, eHicient and durable construction, .by means of whichthe bodies of sheet metal cans or other vessels may be rapidly andcheaply Hanged, in which the Hanging may be done gradually by a kind ofdrawing action without injury to the stock, and in which the cooperatingHanging disks or tools may separate or yield in respect to each other toaccommodate the extra thickness of stock at the side seam of the canbody, and by means of which the can bodies may be provided with uniform,true and perfect flanges so that hermetically tight and perfect doubleseams may be fomed by and between the seaming flanges of the can bodyand of the can body or cover.

My invention consists in the means I employ to practically accomplishthis object or result. That is to say, it consists in a pairof'rotatable cooperating Hanging disks or tools, one having an internalor concave operating face or edge and the other an external or convexHanging face or edge, and one movable or oscillatory in respect to theother, as required to turn the Hange.

It also consists in connection with such Hanging disks or tools inhaving one of them slightly separable from and yieldingly ield againstthe other to adapt the same to accommodate the extra thickness of stockat the side seam of the can body, and in combining therewith a yieldingor cushioned supporting ring or chuck fitting inside the can body tosupport the same in true circular form during the Hanging operation andmovable with the movable Hanging disk or tool and mounted on the rotaryHanging head which carries the two opposing Hanging disks or tools.

My invention also consists in the novel construction of parts anddevices and in the novel combinations of parts and devices herein shownand described and more particularly specified in the claims.

In the accompanying drawing forming a part of this specification, Figure1 is a side elevation of a can body Hanging machine embodying myinvention. Fig. 2 is an end view. Fig. 3 is a horizontal section on line33 of Fig. 1. Fig. t is a detail central vertical section through one ofthe Hanging heads. Fig. 5 is a detail section on line 5-5 of Fig. 4 andFig. 6 is a detail face view of the yielding or cushioned can bodysupporting ring or chuck which is mounted on the rotary Hanging head andwhich fits inside the can body to support the same in true circularshapeduring the Hanging operation. Figs. 7 and 8 are detail diagrammatic faceviews of the cooperating concave and convex Hanging disks or tools; Fig.9 is a detail sectional view of the Hanging tools showing them indiHerent positions from that illustrated in Fig. l; and Figs. 10, 11 and12 are detail views illustrating the operation and its gradual ordrawing like action 111 producing the flange.

In the drawing A represents the frame of the machine.

B is a rotary Hanging head reniovably secured by screw threads b to itsshaft B which is journaled in suitable bearings B on the frame of themachine.

C is the convex faced rotary Hanging disk or tool which is fixed to therotary Hanging head or immovable in respect thereto, the same fitting ina suitable annular recess 6 in the rotary Hanging head B, and having aconvex circular shoulder or Hanging face or edge C fitting inside andengaging the end of the can body X and operating in conjunction with themovable concave Hanging disk or tool D to turn the flange m on the canbody X. This relatively fixed or stationary rotary Hanging disk or tool0 is secured in place on the rotary Hanging head B by a face or wearingplate B which is preferably of brass or like metal and the inner edge ofwhich overlaps the outer edge of the Hanging disk or tool C.

D is the cooperating movable or oscillatory rotary concave Hanging diskor tool, having an inside concave operating face or edge D the samerotating with and being mounted movably upon the rotary Hanging head B,preferably by means of a movable ring D having a circular opening (Zsurrounding the hub b of the rotary flanging head B, and to which theflanging disk or tool D is secured by interengaging flanges (Z (Z andconnecting belts or screws (Z rubber or other elastic cushions orsprings (Z being inserted bet-ween the ring D and the heads (Z of thebolts (Z to enable the tool D to separate slightly or yield laterally inrespect to the cooperating tool C sufiicient-ly to accommodate the extrathickness of the stock at the side seam of the can body. The rotaryconcave fianging disk or tool D is caused to rotate with the flanginghead B by a radial guide pin (Z F is the yielding or cushionedsupporting disk or chuck which flts inside the mouth of the can body Xto support the same in true circular shape during the flanging operationand which moves with the movable concave flanging disk or tool D inrespect to the rotary flanging head B and flanging disk or tool C whilerotating with the rotary flanging head B and flanging'disks or tools CD. This supporting chuck or disk F is preferably held yieldingly inposition as required by anaxially arranged spring F the opposite ends ofwhich are connected to the head B and disk F by connecting buttons f fThe axial spring F cooperates with annular wedging or tapering groovesor faces f (on the disk F) and b (on the rotary flang ing head B) tohold the can body supporting disk or chuckF yieldingly in positionagainst the thrust of the movable flanging disk or tool D. The flangingtools C D have also parallel faces C D respectively at right angles tothe convex face C of the tool C and concave face D of the tool D betweenwhich parallel faces the flange is received as it is turned or formed onthe can body.

The movable concave flanging disk or tool D and the parts which movetherewith are given the necessary oscillating movement in respect to therotary flanging head B, preferably by means of a movable ring or strapGr having a slot 9 and provided with a flange g engaging a flange (Z onthe ring D and which ring or strap Gr 1S connected to a verticallyreciprocating slide G actuated by a crank G on the countershaft Gthrough the connecting rod or pitman G To give a cushioned or yieldingaction to the movable flanging disk or tool D, a spring G is preferablyinterposed between the two parts G and G of the connection between thering or strap G and the slide G The slide G reciprocates in a suitableguide G on the frame of the machine, and it is provided with ahorizontally extending slot or guideway g through which motion iscommunicated to the chuck or clamp disk H by which the can body X isclamped upon the rotary flanging head B and the yielding or movable canbody supporting disk or chuck F carried thereby.

To give the can body clamping or chucking disk H the necessary in andout move ment to clamp the can body and also the necessary up and downmovement with the movable flanging disk or tool D and yielding can bodysupporting chuck or disk F, the disk H is mounted upon an inwardlyswinging and vertically movable lever H having a bent arm 7t furnishedwith a roller 7L fitting in and engaging the horirontal guide 9 of theslide G and which is movably connected to a stationary bracket H on theframe by a pin 7L2 extending through a vertical slot it in the bracket HThe first portion of the downward movement of the slide G thus causesthe arm H to swing inward toward the rotary flanging head B about thepivot 12, as a center and thus clamps the can body, and the furtherdownward movement of the slide G is then caused to impart a paralleldownward movement to the clamp or chuck H and its operating arm H byreason of the slot 7L Locking and releasing levers if 7r pivoted at itif to the stationary bracket H and pivotally connected together at theirmeeting ends, the lever it having a lip 71 overhanging the pivot pin 7Land the lever 705 having a lip it projecting under and en gaging thepivot of the roller 7L serve to lock the lever H in its closed positionwhile permitting it to move down with the flanging disk D and can bodychuck or support F, and serve, on the upward or opening movement of theslide G to permit the arm H and clamp disk H to swing outward to releasethe can.

The driving shaft B is furnished with fast and loose driving pulleys BB" and motion is communicated therefrom to the shaft G through theconnecting chains and sprocket wheels K K I K K K. The machine ispreferably made double or with two rotating flanging heads, one on eachend of the shaft B and the other cooperating parts being, of course,duplicated.
